My KD-49X8305C is being picked up by John Lewis tomorrow. I had no argument from them, especially when i presented them with the following list of issues experienced:
1. Needs unplugging from mains to reboot several times a week to eliminate increased unresponsiveness.
2. Upon first waking up from standby mode the TV informs me that it is not connected to the Internet, then a few seconds later it informs me that it is connected. This has only occurred since the YourView update of 4/11/15. The TV is connected via ethernet to my router at all times. I have had to get a power line ethernet adapter as the TV does not receive 5GHz WiFi signals and so cannot reliably stream 4K content via WiFi.
3. Can take up to five minutes after waking up from standby before I can either change a Freeview channel or alter other settings such as volume. By which time I have missed the weather forecast I can woken the TV up to watch!
4. Have to carefully use the “Back” button to exit apps such as Netflix or Amazon Instant Video otherwise the TV becomes unresponsive and will need a restart via unplugging from the mains.
5. Approximately 30% of the time when putting the TV into standby mode it will wake itself up 20 seconds later, resulting in another attempt to enter standby.
6. Takes up to five seconds to change Freeview channels.
7. Sometimes does not respond to the remote and I have a wait for a couple of minutes before attempting second time.
8. Intense use of the YouView guide can result in the TV becoming so unresponsive that a reboot is required.
9. Volume level via ARC to my Sony HT-RT5 sound bar is very low. Selecting a volume level of 35 out of 50 is required for normal programme viewing (such as the news). This increases to 48-49 out of 50 for a music programme that warrants some umpf (such as Strictly)! My 15 years old 16 inch Sony Wega TV in the kitchen is loader (without the base) than what is produced by this machine. This is a real deal breaker.
10. Still no 5.1 sound on Amazon Instant Video.
11. Occasionally the TV tuner complains that there is no antenna plugged in when attempting to select digital TV but if I first select YouView the TV will find a signal.
12. Generally, as the TV is using a dual core as opposed to the quad core used by other manufactures the machine feels like it is constantly playing “catch up” with the request I make of it.
13. Occasionally when selecting digital TV after using an external HDMI port (such as a Mac mini), the sound completely dies (though a picture is present). The only way to cure this is to reboot the TV.
At least on the positive side I've been given household permission to go even bigger with the replacemet TV. Looking forward to John Lewis delivering my new LG 55UF860V tomorrow.
